I very much doubt you have a blocked inlet manifold passage as I'd image it would cause a lot more damage than a knocking noise. It's a pure guess but maybe an injector is at fault. Do you have access to diagnostics? If not a leakoff test might be a good test.
Like Toms306 says it can be removed but would be a rite pain in the buttocks.
